I’m doing an email sending, using the native wordpress function wp_mail where send multiple concatenated fields in the variable $message, including checkboxes marked by the user. Despite believing to be doing it right, these checkboxes are the only ones that point errors and are not sent, appearing error:
Warning: Invalid argument supplied for foreach() in functions.php line 92
where this line has the following
foreach ( $_POST['salgados_selecionados'] as $key => $value ) {
$message .= $value;
}
the checkbox are several, but an example would be
<input type="checkbox" name="salgados_selecionados" id="232" value="Bolinha com carne seca">
<input type="checkbox" name="salgados_selecionados" id="258" value="Bolinha de queijo">
<input type="checkbox" name="salgados_selecionados" id="256" value="Coxinha">
I used this same idea in another project and it worked.
The problem is in $_POST['salteos_selecionados'] Where is this coming from? a select ? a radio ? a text ? . do this and show what appears : var_dump($_POST['salt_selected'])

I edited the question, they are checkbox. When I var_dump it appears only the last checkbox selected

I changed the name to selected salty[] and now it works. In the first version it was already like this, but I already worked so much in this code that I ended up tidying up without even knowing what was wrong the first time.

The correct thing would be to treat this &_POST you are receiving before sending to a foreach, even for the security of your application.
